Losing 1-0 to Porto in the first leg was really unfortunate for Arsenal as they played quite overwhelmingly but did not score a goal. Porto is always an unpleasant opponent in the UCL, but looking back at the teams entering the qualifying round, this is a much easier opponent for them. Hopefully the Emirates home field will help Arsenal play more confidently and win against Porto in the second leg.
The 1-0 defeat against Porto was not complicated for Arsenal, even though Porto has always been a bad club, that doesn't mean they are difficult to beat. We know that Porto always beat big clubs in the last 16 of the Champions League, but we have to know that the second leg will be played at Arsenal which is expected to be beneficial for Arsenal in getting a goal. At least a 2-0 result is enough to advance Arsenal to the next round, at least to avoid a draw or keep Porto from scoring goals above 2, because that will eliminate Arsenal in the number of away goals. and aggregate goals.
